Stand assembly for a portable electronic device

Abstract

A stand assembly for a portable electronic device is disclosed. The stand assembly enables the portable electronic device to stand horizontally and vertically, as well as standing at an angle. The stand assembly includes a first arm swingably provided by a first hinge on a rear surface side of a chassis, a second arm swingably provided by a second hinge on the rear surface side of the chassis. The stand assembly also includes a connecting section that connects the first arm to the second arm 12 , with the second arm being longer than the first arm.

What is claimed is: 
     
       1. An apparatus comprising:
 a first arm swingably hinged to a rear surface of a chassis of a portable electronic device; 
 a second arm swingably hinged to said rear surface of said chassis, wherein said second arm is longer than said first arm, wherein when said second arm is brought into contact with a placement surface to stand said portable electronic device on said placement surface, a perpendicular line from a center of gravity of said portable electronic device down to said placement surface falls within a triangle drawn by a contact line between said portable electronic device and said placement surface and a distal end of said second arm; and 
 a connecting section connects said first arm and said second arm. 
 
     
     
       2. The apparatus of  claim 1 , wherein said first arm is connected to said chassis via a first hinge, and said second arm is connected to said chassis via a second hinge. 
     
     
       3. The apparatus of  claim 2 , wherein axial directions of rotations of said first hinge of said first arm and said second hinge of said second arm are on a same straight line. 
     
     
       4. The apparatus of  claim 1 , wherein said first arm, said second arm, and said connecting section are provided along an outer periphery of said chassis, wherein said first arm and said second arm are disposed in parallel to each other. 
     
     
       5. A portable electronic device comprising:
 a plate-shaped chassis; and 
 a stand assembly having,
 a first arm swingably hinged to a rear surface of said chassis; 
 a second arm swingably hinged to said rear surface of said chassis, wherein said second arm is longer than said first arm, wherein said first arm is connected to said chassis via a first hinge, and said second arm is connected to said chassis via a second hinge, wherein axial directions of rotations of said first hinge of said first arm and said second hinge of said second arm are on a same straight line; and 
 a connecting section connects said first arm and said second arm. 
 
 
     
     
       6. The portable electronic device of  claim 5 , wherein said first arm, said second arm, and said connecting section are provided along an outer periphery of said chassis, wherein said first arm and said second arm are disposed in parallel to each other. 
     
     
       7. The portable electronic device of  claim 5 , wherein said chassis includes an accommodating groove for accommodating said stand assembly. 
     
     
       8. The portable electronic device of  claim 5 , wherein said chassis includes a regulating section that regulates a swingable range of one of said first and second arms. 
     
     
       9. The portable electronic device of  claim 5 , wherein a magnet is provided on at least one of said first arm, said second arm and said connecting section. 
     
     
       10. The portable electronic device of  claim 5 , wherein a magnet is provided on said chassis. 
     
     
       11. A portable electronic device comprising:
 a plate-shaped chassis; and 
 a stand assembly having
 a first arm swingably hinged to a rear surface of said chassis; 
 a second arm swingably hinged to said rear surface of said chassis, wherein said second arm is longer than said first arm, wherein when said second arm is brought into contact with a placement surface to stand said portable electronic device on said placement surface, a perpendicular line from a center of gravity of said portable electronic device down to said placement surface falls within a triangle drawn by a contact line between said portable electronic device and said placement surface and a distal end of said second arm; and 
 a connecting section connects said first arm and said second arm. 
 
 
     
     
       12. The portable electronic device of  claim 11 , wherein said first arm is connected to said chassis via a first hinge, and said second arm, is connected to said chassis via a second hinge. 
     
     
       13. The portable electronic device of  claim 12 , wherein axial directions of rotations of said first hinge of said first arm and said second hinge of said second arm are on a same straight line. 
     
     
       14. The portable electronic device of  claim 11 , wherein said first arm, said second arm, and said connecting section are provided along an outer periphery of said chassis, wherein said first arm and said second arm are disposed in parallel to each other.
